B&W ammonia engine development

Everllence is aiming to deliver the first ammonia engine, the Everllence B&W ME-LGIA, to a shipyard in 2025. It will be available as newbuild or retrofit. 

Compact design and retrofittable
Everllence
B&W ME-C

Our ME-C engines with electronic controls serve up a host of advantages. You can look forward to superior performance parameters, compactness, fully integrated electronic control as well as the necessary fuel injection pressure and rate shaping at any load. Plus, the ME-C engine can be retrofitted for alternative fuels such as methanol, LPG, methane or ethane as well as ammonia estimated for 2026. 

  • Engine speed: rpm to 56 – 167 
  • Output: 4,350 – 82,440 kW at L1

Low methane slip emissions
Everllence
B&W ME-GI

The ME-GI engine impresses with extremely lowest methane slip and very high fuel efficiency. It is the most environmentally friendly methane-fuelled engine on the market. By the optional use of fuel oil or LNG/bio-methane/SNG, it represents a highly efficient, flexible, propulsion-plant solution. 

  • Engine speed: rpm to 56 – 167 
  • Output: 4,350 – 82,440 kW at L1 
The optimal choice for ethane carriers
Everllence B&W ME-GIE

The technology of the ME-GIE is based on our successful ME-GI engine. This engine can be operated with liquefied ethane gas (LEG) as well as fuel oil – which makes it the standard choice for ethane carriers. This engine offers very competitive fuel oil and gas consumption, plus operational stability and efficiency due to the diesel principle. 

  • Engine speed: 72 – 100 rpm 
  • Output: 8,600 – 21,440 kW at L1

Scalable energy transition
Everllence B&W ME-LGIM

Our ME-LGIM is a dual-fuel engine characterized by its high efficiency and capability of operating on methanol. With a proven record of more than 600,000 operating hours on methanol alone, the engine concept provides a high degree of reliability. When fuelled by green methanol, our ME-LGIM engine can offer truly carbon-neutral propulsion, while reducing sulfur and particle matter emissions significantly at the same time. 

  • Engine speed:  56 – 125 rpm 
  • Output: 6,950 – 82,440 kW at L1
The world's only two-stroke engine fuelled with LPG
Everllence
B&W ME-LGIP

Our ME-LGIP is the only two-stroke dual-fuel engine on the market which can be fuelled with LPG. The low operational costs as well as the simple retrofit solution are particularly convincing.

  • Engine speed: 72 –103 rpm
  • Output: 8,600 – 22,720 kW at L1
